TO ALL, WHOM IT MAY CONCERN:

.Be it known that I, ABRAM SCHENCK, of the town of Ovid, in the countyof Clinton, in the State of Michigan, have invented a new and improvedGrain-Separator and Cleaner; and I do declare that the following is atrue and accurate description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,and being a partof this specification.

Figure 1 is a perspective view of the separator and cleaner.

Figure 2 is a vertical sectional view of the same.

The same letters refer to similar parts in each figure.

This invention consists in ccmbining'with the fans a series 0 arrangedthat the strong currents of air created in the flues ,by force throughthe conductors all impurities, such aschess, cockle, tailings, &c.

To enable those skilled in the art to manufacture this machine, adescription of its eonstructionwill now be given, special referencebeing called to the drawings, and lettersof reference marked thereon. AA, 860-, is a proper frame tofasten the working parts-of the machine. BBare cross-beams or timbers, provided with proper devicesin which runsthefan-shaft C. E is a pulley on the lower end ofthe shaft 0, and whenattached by belting to power, gives motion to it. D D D are hubsattached to the shaft C, and to which are fastened, by proper arms, thewings I II, &c., of the fans. H H H are wind-chests, within whichthefans revolve. Leading from the hoppers M M M to the wind-chests H H Hare theflues NH N, provided with valves G G G, which are to be raised orlowered at pleasure, or as the case may require. From the wind-chests HH H run the conductors O O 0, provided with depressed boxes K K K forthe purpose-of catching any grain that may accidentally be drawn intothe fines. These boxes are provided with hinged bottoms L L L, held inplace by i i be operated upon is poured after the fans have been put inmotion. The current of air created bythe motion of the fans draws thefoul and light st'ufiwhich it-is desired to remove up through the upperflue to the wind-chest whenceit is ejected by the same current of airthrough the upper conductor. Should this air-current, which can beregulated by'the valves Gr, 860., be too strong, and draw into the finesany valuable grain, after passing through thewind-chcst, it will fall tothe floor of'the conductor, and drop into the depressed box attachedthereto. When enough grain has accumulated in this depressed box toovercome the weight J, the valve-bottom L will open and discharge thegrain. The middle and lower flucs, wind-chests, fans, conductors, andhoxcs, with their attachments, repeat the operation described aboveuntil the grain is discharged at P thoroughly cleansed.

What I claim as my invention, and desire to secure by Letters Patent,isf The combination of the frame A with the'crnss-bcams B B, the shaftG, the hubs'D D D, and the wings I I I of the fan, the pulley E, thehoppers F M M M, the lines N NN, the conductorso 00, the depressed boxesK K K, the bottom valves L L L, the'weights and cords J J J, and thevalves G G G, or their cquiva f flues, hoppers, valves, and conductors,so the operation of the fans will draw of and- ABRAM scHEncK.
